DMG Mori NVX 5060

The DMG MORI NVX 5060 is a vertical machining center of the NVX 5000 2nd Generation with 600 × 530 × 510 mm (23.6 × 20.9 × 20.1 in) of travel and an 800 kg (1,763.7 lb) workpiece limit. It has the shortest X travel of three models built on the same Y and Z: the NVX 5080 has 800 mm (31.5 in) of X and the NVX 5100 has 1,050 mm (41.3 in). Parts can be up to 900 mm (35.4 in) long, 600 mm (23.6 in) wide and 510 mm (20.1 in) high.

The structure mixes two kinds of guideway. X and Y run on wide slideways, Z on roller guides. A sliding way has a large contact area and damps vibration well, which is what the table axes need under a heavy cut. DMG MORI states that the wide slideways are there to minimize quadrant projection, the small bump left where an axis reverses during a circular move. Roller guides give the Z-axis low friction for the many short strokes of drilling and pocketing. The column shape is described as reducing thermal displacement.

Two spindle lines are offered. The No. 40 taper speedMASTER is the high-speed choice, and DMG MORI names improved run-out accuracy as its feature. The No. 50 taper powerMASTER is the heavy-duty choice and has thermal expansion compensation by a spindle growth sensor. On a machine with only 600 mm of X, a No. 50 taper says something about the intended work: short, heavy parts in steel or cast iron. The Highlights give no speed, power or torque for either spindle. The spindle unit contains a cartridge that includes the rear bearings, a point DMG MORI lists under replacement of the spindle unit.

Through-spindle coolant, the internal spiral-type chip conveyor and a coolant tank for collecting casting sludge are all options. The door opening is wide and the ceiling part also opens for loading with a crane, which is relevant with an 800 kg (1,763.7 lb) part.
